* opengl: remove unnecessery glflush calls
glflushing forces the driver to break batching and issue commands
prematurely and prevents optimisations like command reordering and
merging.
many glFunctions already internally glflushes and eglsync creation still
has a glflush at end render. so lets reduce the overhead of these calls.
* opengl: reduce glUseProgram calls
apitrace shows cases where the same program gets called multiple times,
add a helper function that keeps track of current program and only call
it once on same program. reduces slight overhead.
* opengl: use more efficient vertex array object
use a more modern vertex array object approach with the shaders, makes
it a onetime setup on shader creation instead of once per drawcall, also
should make the driver not have to revalidate the vertex format on each
call.
* rename ignorezero to ignorealpha
* allow setting ignorealpha value
This commit allows setting a float value (0-1) for the ignorealpha layer rule.
Does not yet have error handling; invalid ignorealpha layer rule will crash Hyprland.
* add brackets i forgot to add
* prevent crash with invalid ignorealpha value
prevents hyprland from immediately crashing with invalid ignorealpha layer rule
does not log
* don't try to set ignoreAlphaValue if alpha value not specified
* add catch to try, reintroduce ignorezero
- added catch after try cuz i was an idiot
- re-add ignorezero as an alternative to ignorealpha to not introduce a breaking change
* add logging for failed ignorealpha layer rule
* fix get ignorealpha's get VALUE
* check npos and use empty()
* rename VALUE cuz no longer const
* format Shader.hpp
* Optionally expose time to screen shaders
Since that collides with damage tracking, it will only be done, when
damage tracking is disabled, meaning this comes at no cost for everyone
not using time.
* Rename m_Timer to m_tGlobalTimer
